An electrode wire is used in arc welding. A speed is selected to make a continuous weld. The electrode melts the metal when it comes in contact with the metal. This helps the other metal to combine with this metal. The metals are cooled to produce a permanent joint. The joint is much stable in case of arc welding. Arc welding is in high usage in the industry. It is recommended that you always clean the surface of both the metals before starting the welding process. Dirt and debris can weaken the strength of the joint. This results in damaged and broken joint in no time.
What is tungsten welding?
In tungsten welding, a tungsten electrode is used to produce the weld. Argon gas is used to protect the metals from any contamination. Filler metal is used to produce a strong joint. Mostly, this technique is employed where there is a requirement to join metal sheets. It can also be used to weld different types of materials and has lesser limitations than other types of welding techniques. There is only a single disadvantage of this welding. This welding technique is complex. It requires a lot of time for a beginner actually to learn the process of welding. It is also a slow process. Plasma cutting machine [เครื่อง ตัด พ ลา ส ม่า, which is the term in Thai] can be used to break the welds if required.
The benefits of MIG welding:
MIG welding is the most used type of welding. There are certain things that MIG welding has that no other welding provides. It also has some disadvantages. But the good thing is that the disadvantages are much lesser if you think of the benefits of MIG welding. Followings are some advantages:
- It is very easy to perform.
- It gives you great speed. Thus, you can do welding in lesser time.
- It also allows you to perform welding in a much cleaner way.
Safety is very important during the welding process. Always ensure that you are using the proper dress and equipment. Use of Light mask [หน้ากาก ปรับ แสง, which is the term in Thai] is of great significance. It helps to keep the eyes protected from harmful rays.
